ive had about 30 or 40 cystoscopies over the years, half of which have been resections for biopsies or tumour removal. had many different symptoms after; bleeding, no bleeding, bleeding 3 weeks later after not bleeding, still bleeding 6 weeks later, microscopic blood at 2 months, scabs, blobs, stringy bits, blockups blah blah blah. I recall the that the hospital literature refers to your urine having a "pinkish" colour for "a few days" after the procedure. Nobody knows, everyone is different. I used to figure that they'd cauterised an area of the bladder, it scabbed over, about 1 - 3 weeks later the scab drops away and this is followed by more bleeding just as would happen if a scab dropped away from a cut on my hand. also, I've learned that debris can sit around in the bottom of the bladder for weeks and weeks before it's flushed out and can be interpreted as "new" material. I tend to not worry too much. If someone's been fiddling with my giblets then I allow for a certain amount of unsettled behaviour down under. That said, I'm not afraid to pester my surgical team if I feel instinctively uneasy about something that's going on. Fortunately I have a lot of trust in my team. Even though I can hear them wince occasionally when they realise it's me on the phone.
